CAVITATION AND THE DIRECT MEASUREMENT OF SOIL SUCTION

The pore water in soils can sustain very high negative pressures (suctions), and it is possible to estimate this pressure using many different indirect methods. However, attempts to measure directly suction greater than one atmosphere are often unsuccessful due to cavitation in the measuring system. It is recognized that water has a high tensile strength, and this characteristic is in conflict with the phenomenon of cavitation observed in measuring systems. The lack of inter-communication between the various sciences involved in measuring negative pressure in liquids has delayed the development of direct suction measurement system for soils. This paper presents a literature review of how and why cavitation occurs within suction measurement systems, and makes recommendations for techniques to reduce the likelihood of cavitation.
